Basis of Presentation	'
	Note 1 - Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements (“financial statements”) include the accounts of Compuware Corporation and its majority owned subsidiaries (collectively, the "Company", “Compuware”, “we”, “our” and “us”). All inter-company balances and transactions have been eliminated in consolidation.  The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, contingencies and results of operations. While management has based their assumptions and estimates on the facts and circumstances existing at September 30, 2014, final amounts may differ from these estimates.
	In the opinion of management of the Company, the accompanying financial statements reflect all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods presented. These financial statements should be read in conjunction with the Company's audited consolidated financial statements and notes thereto for the year ended March 31, 2014 included in the Company's annual report on Form 10-K filed with the Securities and Exchange Commission (“SEC”). The condensed consolidated balance sheet at March 31, 2014 has been derived from the audited financial statements at that date but does not include all information and footnotes required by U.S. GAAP for complete financial statements. The results of operations for interim periods are not necessarily indicative of results expected to be achieved for the full fiscal year.
	Merger Agreement
	On September 2, 2014, the Company entered into an agreement and plan of merger with affiliates of Thoma Bravo, LLC (collectively, “Thoma Bravo”) pursuant to which the Company will become, upon completion of the merger contemplated thereby, a wholly owned subsidiary of Thoma Bravo. The transaction is subject to approval from Compuware's shareholders, regulatory approvals, and other customary closing conditions. The closing of the transaction was also subject to the completion of a distribution of Compuware's shares of Covisint Corporation (“Covisint”), a subsidiary of the Company.  On October 31, 2014, the Company completed the spin-off of its Covisint shares. See note 11 for further discussion of the Covisint spin-off.
	Discontinued Operations
	On January 31, 2014, the Company sold substantially all of the assets and transferred certain liabilities associated with its Changepoint, Professional Services and Uniface business segments to Marlin Equity Partners (“Marlin”).
	At the initial closing on January 31, 2014, Marlin paid a cash payment of $112 million.  During the first quarter of fiscal 2015, the Company paid approximately $8.0 million to Marlin as reimbursement of purchase price related to customer accounts receivable which were retained by the Company in excess of the initially estimated amount.
	The Changepoint, Professional Services and Uniface segment results have been presented as discontinued operations herein for the three and six months ended September 30, 2013. The following table provides the financial results included in income from discontinued operations, net of tax during the periods presented (in thousands):
		Three Months Ended		Six Months Ended
		September 30,		September 30,
		2013		2013
	Revenues	$	55,409	$	112,116
	Operating expenses		44,316		92,248
	Income from operations		11,093		19,868
	Income tax provision		3,881		6,951
	Income from discontinued operations, net of tax	$	7,212	$	12,917
	Non-Controlling Interest
	As of September 30, 2014, the Company owned 82.42 percent of the economic and voting interest in Covisint. The non-controlling equity interest in Covisint is reflected as non-controlling interest in the accompanying consolidated balance sheets and was $16.7 million as of September 30, 2014.  On October 31, 2014, the Company completed the spin-off of its Covisint shares. See note 11 for further discussion of the Covisint spin-off.
	During the six months ended September 30, 2014 the Company purchased approximately 1.4 million Covisint shares in the market and in private transactions. These purchases were made in order for the Company to maintain its 80% or greater ownership of Covisint common stock, a condition to a tax-free spin-off, in anticipation of the expiration of lock-up agreements applicable to holders of non-qualified stock options to acquire Covisint common stock and the subsequent exercise of those options.
	In connection with the Covisint IPO, the Company entered into various agreements relating to the separation of the Covisint business from the rest of Compuware’s businesses, including a master separation agreement, an intellectual property agreement, a registration rights agreement, a shared services agreement and a tax sharing agreement.  All but the master separation agreement and the tax sharing agreement  terminated at the spin-off.
	Basis for Revenue Recognition
	The Company derives its revenue from licensing software products; providing maintenance and support services for those products; providing hosted software; and rendering software related and application services. Our software solutions are comprised of license fees, maintenance fees, subscription fees for hosted software and software related services fees.
	The Company sometimes enters into arrangements that include both software related deliverables (licensed software products, maintenance services or software related services) and non-software deliverables (hosted software or application services). Our hosted software and application services do not qualify as software deliverables because our license grant does not allow the customer the right or capability to take possession of the software. For arrangements that contain both software and non-software deliverables, in accordance with ASC 605 “Revenue Recognition,” the Company allocates the arrangement consideration to the non-software deliverables as a group, and to the software deliverables as a group (the “Deliverable Groups”). The Company determines the selling price to allocate the arrangement consideration to the Deliverable Groups based on the following hierarchy of evidence: vendor specific objective evidence of selling price (“VSOE,” meaning price when sold separately) if available; third-party evidence of selling price if VSOE is not available; or best estimated selling price if neither VSOE nor third-party evidence is available. The Company currently is unable to establish VSOE or third-party evidence of selling price for either our software related deliverables or our non-software deliverables as a group. Therefore, the best estimate of selling price for each Deliverable Group is determined primarily by considering various factors, including, but not limited to stated renewal rates in a contract, if any, the historical selling price of these deliverables in similar stand-alone transactions and pricing practices. Total arrangement consideration is then allocated on the basis of the Deliverable Group’s relative selling price.
	Once the Company has allocated the arrangement consideration between the Deliverable Groups, the Company recognizes revenue as described in the respective software license fees, maintenance fees, subscription fees, services fees and application services fees sections below.
	In order for a transaction to be eligible for revenue recognition, the following revenue criteria must be met: persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable and collectability is reasonably assured. The Company evaluates collectability based on past customer history, external credit ratings and payment terms within customer agreements.
	Software license fees
	The Company's software license agreements provide our customers with a right to use our software perpetually (perpetual licenses) or during a defined term (time-based licenses).
	Assuming all revenue recognition criteria are met, perpetual license fee revenue is recognized using the residual method, under which the fair value, based on VSOE, of all undelivered elements of the agreement (i.e., maintenance and software related services) is deferred. VSOE is based on rates charged for maintenance and software related services when sold separately. The remaining portion of the fee is recognized as license fee revenue upon delivery of the products.
	For revenue arrangements where there is a lack of VSOE for any undelivered elements, license fee revenue is deferred and recognized upon delivery of those elements or when VSOE can be established. However, when maintenance or software related services are the only undelivered elements, the license fee revenue is recognized on a ratable basis over the longer of the maintenance term or the period the software related services are expected to be performed. Such transactions include time-based licenses and certain unlimited capacity licenses, as the Company has not established VSOE for the undelivered elements in these arrangements. In order to comply with Regulation S-X, Rule 5-03(b), which requires product, services and other categories of revenue to be displayed separately on the income statement, the Company separates the license fee, maintenance fee and software related services fee associated with these types of arrangements based on its determination of fair value. The Company applies VSOE for maintenance related to perpetual license transactions and stand-alone software related services arrangements as a reasonable and consistent approximation of fair value to separate license fee, maintenance fee and software related services fee revenue for income statement classification purposes.
	The Company offers flexibility to customers purchasing licenses for its products and related maintenance. Terms of these transactions range from standard perpetual license sales that include one year of maintenance to multi-year (generally two to five years), multi-product contracts. The Company allows deferred payment terms with installments collectable over the term of the contract. Based on the Company’s successful collection history for deferred payments, license fees (net of any financing fees) are generally recognized as revenue as discussed above. In certain transactions where it cannot be concluded that the fee is fixed or determinable due to the nature of the deferred payment terms, the Company recognizes revenue as payments become due. Financing fees are recognized as interest income over the term of the related receivable.
	Maintenance fees
	The Company’s maintenance arrangements allow customers to receive technical support and advice, including problem resolution services and assistance in product installation, error corrections and any product enhancements released during the maintenance period. The first year of maintenance is generally included with all license agreements. Maintenance fees are recognized ratably over the term of the maintenance arrangements, which generally range from one to five years.
	Subscription fees
	Subscription fees relate to arrangements that permit our customers to access and utilize our hosted software delivered on a software-as-a-service (“SaaS”) basis. Subscription fees are deferred upon contract execution and are recognized ratably over the term of the subscription.
	Services fees
	The Company offers implementation, consulting and training services in tandem with the Company’s software solutions.
	Services fees are generally based on hourly or daily rates. Revenues from services are recognized in the period the services are performed provided that collection of the related receivable is reasonably assured.
	Application services fees
	Our application services fees consist of fees related to our Covisint on-demand software including associated services. The arrangements do not provide customers the right to take possession of the software at any time, nor do the arrangements contain rights of return. Many of our application services contracts include a services project fee and a recurring fee for ongoing platform-as-a-service (“PaaS”) operations. Certain services related to these projects have stand-alone value (e.g., other vendors provide similar services) and qualify as a separate unit of accounting. Services that have stand-alone value are recognized as delivered. For those services that do not have stand-alone value, the revenue is deferred and recognized over the longer of the committed term of the subscription agreement (generally one to five years) or the expected period over which the customer will receive benefit (generally five years). For services rendered under fixed-price contracts, revenues are recognized using the proportional performance method and if it is determined that costs will exceed revenue, the expected loss is recorded at the time the loss becomes apparent. The recurring fees are recognized ratably over the applicable service period.
	Deferred Revenue
	Deferred revenue consists primarily of billed and unbilled maintenance and subscription fees related to the future service period of maintenance and subscription agreements in effect at the reporting date. Deferred license, software related services and application services fees are also included in deferred revenue for those arrangements that are being recognized over time. Sales commission costs that directly relate to revenue transactions that are deferred are recorded as “prepaid expenses and other current assets” or non-current “other assets”, as applicable, in the condensed consolidated balance sheets and recognized as "cost of application services" or “sales and marketing” expenses, as applicable, in the condensed consolidated statements of operations over the revenue recognition period of the related customer contracts.

	Research and development (“R&D”) costs from continuing operations, that include primarily the cost of programming personnel, amounted to $21.8 million and $22.1 million for the three months ended September 30, 2014 and 2013, respectively, and $41.8 million and $43.7 million for the six months ended September 30, 2014 and 2013, respectively. R&D costs related to our software solutions are reported as “technology development and support” and for our application services network, the costs are reported as “cost of application services” in the condensed consolidated statements of operations.
	Income Taxes
	The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statements and tax bases of assets and liabilities and net operating loss and credit carryforwards using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the period that includes the enactment date. The Company does not permanently reinvest any earnings in its foreign subsidiaries and recognizes all deferred tax liabilities that arise from outside basis differences in its investment in subsidiaries.
	The Company records net deferred tax assets to the extent it believes these assets will more likely than not be realized. These deferred tax assets are subject to periodic assessments as to recoverability and if it is determined that it is more likely than not that the benefits will not be realized, valuation allowances are recorded which would increase the provision for income taxes. In making such determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations.
	Interest and penalties related to uncertain tax positions are included in the income tax provision.
	The Company’s effective tax rate for the six months ended September 30, 2014 was 33.7% compared to 13.7% for the six months ended September 30, 2013. The effective rate for the six months ended September 30, 2014, reflects a benefit due to the recording of interest income resulting from a refund claim approved by the IRS during the first quarter of fiscal year 2015.  The effective rate for the six months ended September 30, 2013, reflects the recording of a benefit related to stock compensation that was previously expected to not result in a tax deduction.  This benefit resulted due to a change in the Company’s expectation regarding the tax deductibility of compensation for certain officers during the first quarter of fiscal year 2014.
	Cash paid for income taxes was $22.0 million and $17.9 million for the six months ended September 30, 2014 and 2013, respectively.
	Recently Issued Accounting Pronouncements
	In August 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-15, “Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties About An Entity’s Ability to Continue as a Going Concern.”  ASU 2014-15 will require management to assess an entity’s ability to continue as a going concern for each annual and interim reporting period, and to provide related footnote disclosure in circumstances in which substantial doubt exists. This ASU is effective for us for the annual period beginning April 1, 2016 , and we will continue to assess the impact on our consolidated financial statements.
	In May 2014, the FASB issued ASU No. 2014-9, “Revenue from Contracts with Customers (Topic 606)”. This ASU supersedes the revenue recognition requirements in Accounting Standards Codification (“ASC”) 605, Revenue Recognition. ASU No. 2014-9 will require an entity to recognize revenue when it transfers promised goods or services to customers using a five-step model that requires entities to exercise judgment when considering the terms of the contracts. This ASU is effective for us beginning April 1, 2017 and can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption.  The Company has not yet evaluated the impact of the update on its financial statements.
	In April 2014, the FASB issued ASU No. 2014-8, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360) — Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” ASU No. 2014-8 changes the requirements for reporting discontinued operations to only allow presentation of a disposal of an entity or component of an entity as a discontinued operation if it represents a strategic shift that has (or will have) a major effect on an entity’s operations or financial results. This ASU is effective for the first annual period beginning after December 15, 2014. The impact of this update on the Company’s financial statements will depend on future changes in operations.
	In March 2013, the FASB issued ASU No. 2013-05, “Foreign Currency Matters (Topic 830) — Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity.” ASU No. 2013-05 resolves the diversity in practice about whether Subtopic 810-10, Consolidation—Overall, or Subtopic 830-30, Foreign Currency Matters—Translation of Financial Statements, applies to the release of the cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity. This ASU was effective prospectively for the first annual period beginning after December 15, 2013. The adoption of ASU No. 2013-05 did not have a significant impact on the Company’s consolidated balance sheet, statement of operations or cash flows.

Restructuring Charges [Abstract]	'
Restructuring Charges	'
	Note 9 – Restructuring Charges
	In February 2013, the Company approved the initial phase of a restructuring plan designed to achieve cost savings. In January 2014, the Company announced the final phase of its restructuring plan designed to reduce the Company’s annual cost base and substantially improve the Company’s operating margins, increasing the aggregate targeted annualized cost savings to a total of $110 million to $120 million. This final phase includes additional reductions in the global workforce primarily across all general, administrative and shared services divisions of the Company, along with the early termination of certain operating leases and the closing or reduction in size of office facilities worldwide.
	These cost reduction efforts, which are expected to be substantially completed by the end of fiscal 2015, are expected to result in cumulative charges of $50 million to $60 million. Substantially all of the estimated charges will result in future cash expenditures.
	During the three and six months ended September 30, 2014, the Company recorded a charge of approximately $2.3 million and $5.2 million, respectively, for costs associated with these reductions, primarily related to severance costs for 30 terminated employees and facilities reductions. The timing of additional charges is dependent upon certain actions to be taken in the future. During the three and six months ended September 30, 2013, the Company recorded a charge of approximately $219,000 and $5.0 million, respectively, for costs associated with these reductions, primarily related to severance costs for 78 terminated employees.
	The following table summarizes the restructuring accrual as of March 31, 2014 and changes to the accrual during the three and six months ended September 30, 2014 (in thousands):
		Employee Termination Benefits			Lease Abandonment Costs			Other			Total Restructuring Activity

	As of September 30, 2014, substantially all of the restructuring accrual was recorded in current “accrued expenses” in the condensed consolidated balance sheets.
	The accruals for employee termination benefits at September 30, 2014 primarily represent the amounts to be paid to employees that have been terminated as a result of initiatives described above.
	The accruals for lease abandonment costs at September 30, 2014 represent the expected payments related to leases that have been terminated before the end of the contractual term. For terminated operating leases, the accrual includes the remaining fair value of lease obligations for exited and demised locations, as determined at the cease-use dates of those facilities, net of estimated sublease income that could be reasonably obtained in the future, and will be paid out over the remaining lease terms, the last of which ends in fiscal 2017. Projected sublease income is based on management’s estimates, which are subject to change.

Contingencies	'
	Note 10 – Contingencies
	Effective October 1, 2013, the Company terminated a post-retirement consulting agreement with its former Chairman for “Cause”, and all outstanding equity awards he held terminated pursuant to the applicable agreements. On November 13, 2013, the former Chairman filed a lawsuit against the Company regarding his termination. The Company and the former Chairman have agreed to binding arbitration of this dispute. The accounting impact of the termination of the vested and unvested stock options and unvested RSUs was recognized in other income net of a portion of the estimated liability related to the pending lawsuit. The Company believes its accruals as of September 30, 2014, related to this dispute are reasonably estimated.
	A number of putative class action complaints have been filed by purported shareholders against the Company related to the merger agreement with Thoma Bravo.  The complaints generally allege that the Board of Directors breached its fiduciary duties in negotiating and approving the proposed merger transaction.  The Company believes these lawsuits are without merit and intends to vigorously defend against these claims.
	The Company has been named as a co-defendant in a consolidated class action complaint filed against Covisint, its directors and certain officers at the time of Covisint's initial public offering ("IPO") alleging violation of securities laws in connection with Covisint's IPO and seeking unspecified damages.  The Company believes the lawsuit is without merit and intends to vigorously defend against it.
	The Company is subject to various legal actions and claims incidental to its business. Litigation is subject to many uncertainties and the outcome of individual litigated matters is not predictable with assurance. Based on information currently known, the Company does not believe these will have a material impact on the Company’s financial position, results of operations or cash flows.

Subsequent Events	'
	Note 11 – Subsequent Events
	On October 31, 2014, the Company distributed all of its 31,384,920 shares of Covisint common stock as a pro rata dividend on shares of Compuware common stock, and on shares of Compuware common stock deliverable under restricted stock units relating to Compuware common stock (“the Distribution”).
	Based on the number of Covisint shares outstanding owned by the Company and shares deliverable under RSUs as of October 20, 2014, the record date for the distribution, holders of Compuware common stock received 0.14025466 shares of Covisint common stock in the distribution with respect to each outstanding share of Compuware common stock they owned as of the close of business on the record date, and holders of RSUs received 0.14025466 shares of Covisint common stock in the distribution with respect to each share of Compuware common stock deliverable under the RSUs they held at the close of business on the record date.
	Fractional shares of Covisint common stock were not distributed to Compuware shareholders or RSU holders. Instead, the fractional shares of Covisint common stock were aggregated and sold in the open market, with the net proceeds distributed pro rata in the form of cash payments to Compuware shareholders and RSU holders who would otherwise receive Covisint fractional shares.
	In anticipation of the merger with Thoma Bravo, Compuware intends to treat the distribution as a taxable distribution of the Covisint common stock by Compuware for U.S. federal income tax purposes.  Any corporate-level income tax incurred on the distribution if the acquisition by Thoma Bravo is completed will be paid by Compuware.
	The distribution of shares of Covisint common stock was made in book entry form, and no physical share certificates of Covisint were issued. An information statement describing the distribution was mailed to Compuware stockholders. Compuware shareholders were not required to pay cash or other consideration for the shares of Covisint common stock distributed to them or surrender or exchange their shares of Compuware common stock to receive the distribution.
	As a result of this distribution, the Company no longer owns any shares of Covisint common stock.  The operating results of Covisint will be reflected in discontinued operations in the third quarter of fiscal year 2015.
	As of September 30, 2014, the carrying value of the Covisint assets and liabilities included in our consolidated balance sheet were as follows (in thousands):

	On January 31, 2014, the Company sold substantially all of the assets and transferred certain liabilities associated with its Changepoint, Professional Services and Uniface business segments to Marlin Equity Partners (“Marlin”).
	At the initial closing on January 31, 2014, Marlin paid a cash payment of $112 million.  During the first quarter of fiscal 2015, the Company paid approximately $8.0 million to Marlin as reimbursement of purchase price related to customer accounts receivable which were retained by the Company in excess of the initially estimated amount.
	The Changepoint, Professional Services and Uniface segment results have been presented as discontinued operations herein for the three and six months ended September 30, 2013.

Non-controlling Interest	'
	Non-Controlling Interest
	As of September 30, 2014, the Company owned 82.42 percent of the economic and voting interest in Covisint. The non-controlling equity interest in Covisint is reflected as non-controlling interest in the accompanying consolidated balance sheets and was $16.7 million as of September 30, 2014.  On October 31, 2014, the Company completed the spin-off of its Covisint shares. See note 11 for further discussion of the Covisint spin-off.
	During the six months ended September 30, 2014 the Company purchased approximately 1.4 million Covisint shares in the market and in private transactions. These purchases were made in order for the Company to maintain its 80% or greater ownership of Covisint common stock, a condition to a tax-free spin-off, in anticipation of the expiration of lock-up agreements applicable to holders of non-qualified stock options to acquire Covisint common stock and the subsequent exercise of those options.
	In connection with the Covisint IPO, the Company entered into various agreements relating to the separation of the Covisint business from the rest of Compuware’s businesses, including a master separation agreement, an intellectual property agreement, a registration rights agreement, a shared services agreement and a tax sharing agreement.  All but the master separation agreement and the tax sharing agreement  terminated at the spin-off.
Basis for Revenue Recognition	'
	Basis for Revenue Recognition
	The Company derives its revenue from licensing software products; providing maintenance and support services for those products; providing hosted software; and rendering software related and application services. Our software solutions are comprised of license fees, maintenance fees, subscription fees for hosted software and software related services fees.
	The Company sometimes enters into arrangements that include both software related deliverables (licensed software products, maintenance services or software related services) and non-software deliverables (hosted software or application services). Our hosted software and application services do not qualify as software deliverables because our license grant does not allow the customer the right or capability to take possession of the software. For arrangements that contain both software and non-software deliverables, in accordance with ASC 605 “Revenue Recognition,” the Company allocates the arrangement consideration to the non-software deliverables as a group, and to the software deliverables as a group (the “Deliverable Groups”). The Company determines the selling price to allocate the arrangement consideration to the Deliverable Groups based on the following hierarchy of evidence: vendor specific objective evidence of selling price (“VSOE,” meaning price when sold separately) if available; third-party evidence of selling price if VSOE is not available; or best estimated selling price if neither VSOE nor third-party evidence is available. The Company currently is unable to establish VSOE or third-party evidence of selling price for either our software related deliverables or our non-software deliverables as a group. Therefore, the best estimate of selling price for each Deliverable Group is determined primarily by considering various factors, including, but not limited to stated renewal rates in a contract, if any, the historical selling price of these deliverables in similar stand-alone transactions and pricing practices. Total arrangement consideration is then allocated on the basis of the Deliverable Group’s relative selling price.
	Once the Company has allocated the arrangement consideration between the Deliverable Groups, the Company recognizes revenue as described in the respective software license fees, maintenance fees, subscription fees, services fees and application services fees sections below.
	In order for a transaction to be eligible for revenue recognition, the following revenue criteria must be met: persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable and collectability is reasonably assured. The Company evaluates collectability based on past customer history, external credit ratings and payment terms within customer agreements.
Software license fees	'
	Software license fees
	The Company's software license agreements provide our customers with a right to use our software perpetually (perpetual licenses) or during a defined term (time-based licenses).
	Assuming all revenue recognition criteria are met, perpetual license fee revenue is recognized using the residual method, under which the fair value, based on VSOE, of all undelivered elements of the agreement (i.e., maintenance and software related services) is deferred. VSOE is based on rates charged for maintenance and software related services when sold separately. The remaining portion of the fee is recognized as license fee revenue upon delivery of the products.
	For revenue arrangements where there is a lack of VSOE for any undelivered elements, license fee revenue is deferred and recognized upon delivery of those elements or when VSOE can be established. However, when maintenance or software related services are the only undelivered elements, the license fee revenue is recognized on a ratable basis over the longer of the maintenance term or the period the software related services are expected to be performed. Such transactions include time-based licenses and certain unlimited capacity licenses, as the Company has not established VSOE for the undelivered elements in these arrangements. In order to comply with Regulation S-X, Rule 5-03(b), which requires product, services and other categories of revenue to be displayed separately on the income statement, the Company separates the license fee, maintenance fee and software related services fee associated with these types of arrangements based on its determination of fair value. The Company applies VSOE for maintenance related to perpetual license transactions and stand-alone software related services arrangements as a reasonable and consistent approximation of fair value to separate license fee, maintenance fee and software related services fee revenue for income statement classification purposes.
	The Company offers flexibility to customers purchasing licenses for its products and related maintenance. Terms of these transactions range from standard perpetual license sales that include one year of maintenance to multi-year (generally two to five years), multi-product contracts. The Company allows deferred payment terms with installments collectable over the term of the contract. Based on the Company’s successful collection history for deferred payments, license fees (net of any financing fees) are generally recognized as revenue as discussed above. In certain transactions where it cannot be concluded that the fee is fixed or determinable due to the nature of the deferred payment terms, the Company recognizes revenue as payments become due. Financing fees are recognized as interest income over the term of the related receivable.
Maintenance Fees	'
	Maintenance fees
	The Company’s maintenance arrangements allow customers to receive technical support and advice, including problem resolution services and assistance in product installation, error corrections and any product enhancements released during the maintenance period. The first year of maintenance is generally included with all license agreements. Maintenance fees are recognized ratably over the term of the maintenance arrangements, which generally range from one to five years.
Subscription fees	'
	Subscription fees
	Subscription fees relate to arrangements that permit our customers to access and utilize our hosted software delivered on a software-as-a-service (“SaaS”) basis. Subscription fees are deferred upon contract execution and are recognized ratably over the term of the subscription.
Services fees	'
	Services fees
	The Company offers implementation, consulting and training services in tandem with the Company’s software solutions.
	Services fees are generally based on hourly or daily rates. Revenues from services are recognized in the period the services are performed provided that collection of the related receivable is reasonably assured.
Application services fees	'
	Application services fees
	Our application services fees consist of fees related to our Covisint on-demand software including associated services. The arrangements do not provide customers the right to take possession of the software at any time, nor do the arrangements contain rights of return. Many of our application services contracts include a services project fee and a recurring fee for ongoing platform-as-a-service (“PaaS”) operations. Certain services related to these projects have stand-alone value (e.g., other vendors provide similar services) and qualify as a separate unit of accounting. Services that have stand-alone value are recognized as delivered. For those services that do not have stand-alone value, the revenue is deferred and recognized over the longer of the committed term of the subscription agreement (generally one to five years) or the expected period over which the customer will receive benefit (generally five years). For services rendered under fixed-price contracts, revenues are recognized using the proportional performance method and if it is determined that costs will exceed revenue, the expected loss is recorded at the time the loss becomes apparent. The recurring fees are recognized ratably over the applicable service period.
Deferred Revenue	'
	Deferred Revenue
	Deferred revenue consists primarily of billed and unbilled maintenance and subscription fees related to the future service period of maintenance and subscription agreements in effect at the reporting date. Deferred license, software related services and application services fees are also included in deferred revenue for those arrangements that are being recognized over time. Sales commission costs that directly relate to revenue transactions that are deferred are recorded as “prepaid expenses and other current assets” or non-current “other assets”, as applicable, in the condensed consolidated balance sheets and recognized as "cost of application services" or “sales and marketing” expenses, as applicable, in the condensed consolidated statements of operations over the revenue recognition period of the related customer contracts.
Research and Development	'
	Research and Development
	Research and development (“R&D”) costs from continuing operations, that include primarily the cost of programming personnel, amounted to $21.8 million and $22.1 million for the three months ended September 30, 2014 and 2013, respectively, and $41.8 million and $43.7 million for the six months ended September 30, 2014 and 2013, respectively. R&D costs related to our software solutions are reported as “technology development and support” and for our application services network, the costs are reported as “cost of application services” in the condensed consolidated statements of operations.
Income Taxes	'
	Income Taxes
	The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statements and tax bases of assets and liabilities and net operating loss and credit carryforwards using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the period that includes the enactment date. The Company does not permanently reinvest any earnings in its foreign subsidiaries and recognizes all deferred tax liabilities that arise from outside basis differences in its investment in subsidiaries.
	The Company records net deferred tax assets to the extent it believes these assets will more likely than not be realized. These deferred tax assets are subject to periodic assessments as to recoverability and if it is determined that it is more likely than not that the benefits will not be realized, valuation allowances are recorded which would increase the provision for income taxes. In making such determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations.
	Interest and penalties related to uncertain tax positions are included in the income tax provision.
	The Company’s effective tax rate for the six months ended September 30, 2014 was 33.7% compared to 13.7% for the six months ended September 30, 2013. The effective rate for the six months ended September 30, 2014, reflects a benefit due to the recording of interest income resulting from a refund claim approved by the IRS during the first quarter of fiscal year 2015.  The effective rate for the six months ended September 30, 2013, reflects the recording of a benefit related to stock compensation that was previously expected to not result in a tax deduction.  This benefit resulted due to a change in the Company’s expectation regarding the tax deductibility of compensation for certain officers during the first quarter of fiscal year 2014.
	Cash paid for income taxes was $22.0 million and $17.9 million for the six months ended September 30, 2014 and 2013, respectively.
Recently Issued Accounting Pronouncements	'
	Recently Issued Accounting Pronouncements
	In August 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-15, “Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties About An Entity’s Ability to Continue as a Going Concern.”  ASU 2014-15 will require management to assess an entity’s ability to continue as a going concern for each annual and interim reporting period, and to provide related footnote disclosure in circumstances in which substantial doubt exists. This ASU is effective for us for the annual period beginning April 1, 2016 , and we will continue to assess the impact on our consolidated financial statements.
	In May 2014, the FASB issued ASU No. 2014-9, “Revenue from Contracts with Customers (Topic 606)”. This ASU supersedes the revenue recognition requirements in Accounting Standards Codification (“ASC”) 605, Revenue Recognition. ASU No. 2014-9 will require an entity to recognize revenue when it transfers promised goods or services to customers using a five-step model that requires entities to exercise judgment when considering the terms of the contracts. This ASU is effective for us beginning April 1, 2017 and can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption.  The Company has not yet evaluated the impact of the update on its financial statements.
	In April 2014, the FASB issued ASU No. 2014-8, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360) — Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” ASU No. 2014-8 changes the requirements for reporting discontinued operations to only allow presentation of a disposal of an entity or component of an entity as a discontinued operation if it represents a strategic shift that has (or will have) a major effect on an entity’s operations or financial results. This ASU is effective for the first annual period beginning after December 15, 2014. The impact of this update on the Company’s financial statements will depend on future changes in operations.
	In March 2013, the FASB issued ASU No. 2013-05, “Foreign Currency Matters (Topic 830) — Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity.” ASU No. 2013-05 resolves the diversity in practice about whether Subtopic 810-10, Consolidation—Overall, or Subtopic 830-30, Foreign Currency Matters—Translation of Financial Statements, applies to the release of the cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity. This ASU was effective prospectively for the first annual period beginning after December 15, 2013. The adoption of ASU No. 2013-05 did not have a significant impact on the Company’s consolidated balance sheet, statement of operations or cash flows.
